Description

Integrated wire harness for household washing machine

Technical Field

The utility model belongs to the technical field of the pencil, concretely relates to integrated nature pencil for domestic washing machine

Background

At present, a washing machine is a common household appliance in people's daily life, and is a device for washing clothes by electric energy, and generally, the washing machine includes: a tub for holding washing water; a rotating tub rotatably installed inside the tub; a pulsator rotatably installed at the bottom of the rotary tub; a motor and a clutch configured to rotate the rotary tub and the pulsator; and the balance ring is arranged above the rotary barrel, and is used for supplementing weight when the rotary barrel rotates so as to keep balance. When the rotary tub and the pulsator are rotated in a state in which laundry and detergent are introduced into the rotary tub, the pulsator stirs wash water together with the laundry introduced into the rotary tub, thereby removing dirt from the laundry. Due to such a way of decontaminating the laundry, when the weight of the laundry in the washing machine approaches a rated amount, the load of the motor increases, the temperature of the motor rises, and finally the motor windings of the motor burn out. Although some washing machine manufacturers add a protection module in the washing machine to ensure the normal operation of the motor, the protection module can lose the protection function due to severe moisture because the interior of the washing machine is in a humid environment for a long time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving prior art's not enough, provide an integrated nature pencil for domestic washing machine, including main pencil and a plurality of branch pencil, main pencil and branch pencil between be equipped with the seal housing who is equipped with the PCB circuit board, the PCB circuit board on be equipped with the commentaries on classics of being used for realizing current conversion between main pencil and the branch pencil and flow the module, the commentaries on classics flow in the module and be equipped with the frequency conversion module, seal housing in still be equipped with current sampler, current sampler link to each other with the main pencil to be connected with commentaries on classics flow the module communication simultaneously.

Furthermore, the main wire harness and the branch wire harness are wrapped by silicone rubber layers.

In order to facilitate the disassembly and replacement of the main wire harness, further, the main wire harness is connected with the sealing shell through the incoming line conductive tube.

In order to facilitate the disassembly and replacement work of the branch wire harness, furthermore, the branch wire harness is connected with the sealing shell through the outgoing conductive pipe.

Further, a waterproof insulating coating is provided on the sealing case.

Furthermore, the PCB circuit board is also provided with a communication module which is responsible for information communication and transmits the diversion information of the diversion module to a man-machine interaction panel of the washing machine.

Furthermore, the wiring ends of the main wiring harness and the branch wiring harness are provided with fool-proof terminals.

Has the advantages that: the utility model discloses an integrated nature pencil for domestic washing machine, this integrated nature pencil has solved washing machine protection module and has been in the problem of easily taking place the damage in the humid operational environment for a long time through add the seal housing who is equipped with PCB circuit board and current sampler between main line pencil and branch pencil, has solved the motor simultaneously through PCB circuit board and current sampler, has leaded to this problem of motor winding burnout owing to the too big reason of load.

Drawings

FIG. 1 is a structural schematic view of an integrated wiring harness for a household washing machine;

in the figure: 1. main wiring harness 11, incoming line conductive tube 2, branch wiring harness 21, outgoing line conductive tube 3, sealing shell 31, PCB circuit board 32, current sampler 4 and fool-proof terminal

Detailed description of the preferred embodiments

In order to deepen the understanding of the present invention, the present invention is described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1, an integrated wiring harness for a household washing machine comprises a main wiring harness 1 and a plurality of branch wiring harnesses 2, wherein a sealing shell 3 provided with a PCB 31 is arranged between the main wiring harness 1 and the branch wiring harnesses 2, in order to facilitate the disassembly and replacement work of the main wiring harness 1 and the branch wiring harnesses 2, the main wiring harness 1 is connected with the sealing shell 3 through an incoming conductive pipe 11, and the branch wiring harnesses 2 are connected with the sealing shell 3 through an outgoing conductive pipe 21.

PCB circuit board 31 on be equipped with and be used for realizing the commentaries on classics module of current conversion between main pencil 1 and the branch pencil 2, the commentaries on classics module in be equipped with frequency conversion module, sealed housing 3 in still be equipped with current sampler 32, current sampler 32 and main pencil 1 link to each other to be connected with commentaries on classics module communication simultaneously.

In this embodiment, the main wire harness and the branch wire harness are wrapped with silicone rubber layers.

In this embodiment, the sealing housing is provided with a waterproof insulating coating.

In this embodiment, the PCB 31 is further provided with a communication module, and the communication module is responsible for information communication and transmits the diversion information of the diversion module to the human-computer interaction panel of the washing machine.

In this embodiment, the terminals of the main wire harness 1 and the branch wire harness 2 are both provided with fool-proof terminals 4.

The working condition is as follows: as shown in fig. 1, when the weight of the laundry in the washing machine approaches the rated amount, the load of the motor increases, the current on the main beam 1 increases, the current taken by the current sampler 32 is greater than the protection current, the current sampler 32 sends a feedback signal to the PCB 31, the switching module on the PCB 31 changes the on-off relationship between the main beam and the different branch beams, and the frequency conversion module in the switching module changes the power supply to adjust the load of the motor, thereby achieving the purpose of protecting the motor.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
